What supporting documentation is required to be filed with Schedule RT?
If there is not enough space on Schedule RT to list all entities to which you paid, accrued, or incurred expenses, submit with Schedule RT a supplemental schedule to identify those additional entities and provide the information required on Schedule RT regarding those expenses. You must also submit a supplemental schedule for any related entity expenses other than interest, rent, or royalty expenses; management or service fees; or inventory purchases; if the total amount of such expenses paid, accrued, or incurred to related entities is more than 10% of total expenses (including cost of goods sold) claimed for the taxable year. See the instructions for Schedule RT, Part I, line 4c for details of the information that must be included in this supplemental schedule. You may also submit any other documentation you believe would enhance the Department′s understanding of the transactions. However, this additional documentation is not required.
